Brodmanns Areas + Some other things Flashcards
Brocas aphasia characteristics-
comprehension intact but fluency and repetition not
Wernickes aphasia characteristics-
fluency intact but repetition and comprehension not
Primary motor cortex –> # & if lesion?:
- Precentral gyrus (M1) -4
- contralateral weakness, spastic paralysis, hyperreflexia
premotor and supplementary motor –> # & if lesion?:
- superior and middle frontal gyri (M2) - 6
- apraxia
frontal eye field –> # & if lesion?:
- superior and middle frontal gyri of pre-frontal cortex - 8
- disruption of some of the most complex aspects of behavior
brocas area –> # & if lesion?:
- opercular and triangular parts of inferior frontal gyrus - 44
- nonfluent, motor, expressive - COMPREHENSION INTACT
primary somatosensory cortex –> # & if lesion?:
- post central gyrus - 3,1,2
- loss of tactile discriminatory and proprioception on CONTRALATERAL side - pain not elicited, abolished or relieved
somatosensory association area –> # & if lesion?:
- superior parietal lobule - 5.7
- tactile agnosia, astereognosis, neglect syndrome
primary visual cortex–> # & if lesion?:
- banks of calcarine sulcus (V1) - 17
- initial processing from both eyes gone
cortex surrounding area (vision info from primary vision cortex) –> # & if lesion?:
- cortex surrounding area17 - 18,19
- visual agnosia, achromatopsia, akinetopsia
primary auditory area–> # & if lesion?:
-superior temporal gyrus (A1) - 41 - Granular cortex
auditory association area –> # & if lesion?:
-superior temporal gyrus (A1) - 42
Wernickes area –> # & if lesion?:
- superior temporal gyrus - 39,22
- babbled not coherent speech - FLUENCY INTACT
apraxia
given command and they understand and want to do it but cant execute
aphasia
cant comprehend and formulate language
